This, invention relates to an improved hand cleaning composition. Moreparticularly the invention concerns an improvedpenct rating andingrained dirt removing com position of essentially unsaponified naturalfats and oils in combination with other ingredients which will removeprinters ink, deep ingrained grease, oil and dirt or cement dust fromchapped hands and allows nature. to elfect a normal skin repair underclean and antiseptic conditions. As all laborers and mechanics areaware, grease and oil grime from mechanical labor becomes ingrained inthe cracks and crevices of the hands and fingers. Normally a combinationof saponified soap, detergent or solvent, as gasoline or the like, isused to, clean otf the oil and dirt. As

is generallyknown, such soaps detergents and solvents Accordingly, theprincipal object of this invention is to provide an improved skincleaning and disinfecting composition which removes ingrained grease,dirt and oil grime from the cracks and crevices of chapped handswithoutuncomfortable irritation to dirty open cracks in the skin. r I 7 Anotherobject of this invention is to-provide an improved hand cleaningcomposition of strong cleansing action and yet of mild and soothingbenefit to hands which have remained chapped and rough through'years ofmechanical labor, as in automotive'repair work.=-

An additional object of this invention. is to provide a cleansingcomposition which can be lefton the hands or impregnated into glovesworn on the hands without irritation. r a Other objects and advantageswill be apparent from the following description.

For those who only occasionally soil their hands with temporary lightmechanical labor we have prepared a cleaning composition of thefollowingingredients:

FORMULA I Parts by weight Natural fats and oils 80.0Bis-(2-hydroxy-3,5,6-trichlorophenyl)methane 0.8 N3-2C03.10H2O 3-5Filler, inert material 15.7 Deodorant material 0.1

For those who regularly are employed in automotive or similar repairwork and have the dirt and grime more deeply embedded in their hands,the following cleaning composition is preferred:

FORMULA II Parts by weight Natural fats and oils 80.0Bis-(2-hydroxy-3,5,6-trichlorophenyl) methane 0.8 N3-2C03.10H2O Filler,inert material 0.2 Deodorant material 0.1

In Formula I, the bis-(2-hydroxy-3,5,6-trichlorophenyl) methane can beincreased to 1.6 parts to provide a more bacteriostatic preparation. Thehydrated sodium carbonate can be increased to 15 parts, or used in therange of about 0.5 parts to 25 parts with a relative addition orreduction in the filler and inert material. Also, the total base saltmaterial as hydrated sodium carbonate can be entirely substituted forby, or combined in all percentages with, sodium tetraborate (Na O.2B O;l0H O), or hydrated magnesium sulfate, or mixtures of the same.

In Formula II, the bis-(2-hydroxy-3,5,6-trichlorophenyl) methane canalso be increased. to 1.6 parts to provide a more bacteriostaticpreparation. The hydrated sodium carbonate can be increased to 25 parts,with relative and respective reductions of the natural fats and oil andfor the filter and inert material portions. Again, hydrated magnesiumsulfate and/or sodium tetraborate can be mixed or combined in all parts,or each substituted entirely for the hydrated sodium carbonate.

In preparing the above mixtures the natural fats and oils arethoseobtained from animal, vegetable, marine and mineral sources and ofthe character of semi-drying and non-drying fatty oil material in theform primarily of fatty acids and esters having chains of C to Cunsaponified carbon atoms, including sterols. For example, the naturalfats and oils may be those derived from bear,

swine, sheep, cattle, soy beans, peanuts, corn, olive,

whales, fish oils, and similar straight chain syntheticprodnets ofpetroleum and the like sources, as known to the art. Included in theinert material may be cellulose which may be natural cellulose or anorganic short chain derivative, as methyl or ethyl cellulose and thelike, or a sodium or potassium salt derivative of such, as is known tothe art. The inert material may be added in about 0 to about 18 partsand is preferably added in the range of about 8.4.

parts to 18.7 parts in the form of a mild abrasive as fine sawdust,pumice, or other and like mild skin abrasive as is known to the soapmaking art. A small amount, upto about 1 part oil of cloves, or othersuitable deodorant, or

ingredients soften the solid fat, keep it in soft and flexible conditionfor working with the hands and fingers as a cleansing composition. Afterproper working the dirt and cleaning composition can be easily washedoff with warm water, or normal soap and water. Many have found itadvantagcous to first clean their hands of cement dust, grime, or greaseand dirt, then apply a light coating and wear gloves. This has affordeda soothing effect to badly cracked and chapped hands. Then, by keepingthe hands clean with the above composition, they become relieved of thechapped condition.

Further, it has ben found that by covering the hands with a lightcoating of the composition, before work is begun, a faster cleaningresults and hands that are normally in chapped condition are lesssubject to chapping.

For description of a specific and preferred formula, the fat is amixture of solid and liquid animal glycerides, fatty acids, and theiresters ranging from C3H7COOH to C3H5(OCOC15H3)(OCOC17H33)(OCOC17H35),the 311i mal cholesterol C H O, or sterols (cyclic alcohols). Such fats,as indicated, are preferably mixed in a fluid state With the balance ofthe composition components and forms a thick creamy mass ready forapplication and use. The proportions are as indicated in parts byweight. Otherwise the parts by Weight may be expressed in pounds orgrams and calculated in percentage ratio for making any size batchdesired.

Having thus described our improvement in hand cleaning compositions itwill be apparent that the components may be varied slightly andsubstituted in the relationship described and embodied therein.

We claim:

1. A hand-cleaning skin-smoothing and chapped skinrelieving compositionconsisting essentially of a thick creamy mixture of about 80.0 parts ofnatural oils and fats; not more than 1.6 parts and not less than 0.8part of bis(3,5,6-trichloro-2-hydroxy-phenyl) methane; not more than 25parts and not less than 0.5 part of a basic salt selected from the groupconsisting of sodium carbonate decahydrate, sodium tetraborate andmagnesium sulfate hydrate; not less than 0.2 part and not more than 18.7parts of an inert material, employed as a filler and mild :4 I abrasive,selected from the group consisting of fine sawdust, pumicestone dust,cellulose, methyl. cellulose and ethyl cellulose; all parts being byweight and the parts totaling 100.00.
